Procedure: centrifuge test for oil bs&w cut ‐ 3 ‐ date of preparation: september 1 2004 date of revision: september 1 if it comes back in the same range and is high or low look for reasons for the change and contact your foreman. Sampling procedure for api and bs&w prepared by mopu lab technologist kumar 1 sampling for both api and bs&w 2 plastic bottles must not be used for sampling as there is a risk of a build-up of static charge and the container cannot be earthed to ground. Whether your are mixing, sampling or measuring bs & w with online traditional or newer methods of oil dielectric determination you can easy correlate your results in the field which not only. Bs&w is determined using astm standard d96, d4007 or the api document sediment and water, chapter 10, section 2, 'determination of water and sediment in crude oil by the centrifuge method other methods available for water in crude oil are astm d4377, d4928, ip386. Oil sampling procedure to enable efficient and accurate analysis the following information needs to be provided with the oil sample, if possible on the label procedure - centrifuge test for oil bs&w cut - â€.
Determine the bs & w by the centrifuge method (sample diluted 1/1 with toluene or gasoline) with addition of 1 drop of alken 862 demulsifier while running the above test, run a simultaneous blank test, without the addition of alken 862 demulsifier. Multiply the reading obtained by 2 = s&w innage - height of oil level from tank bottom or fixed datum plate upward to surface of oil in tank outage - measurement from fixed reference point at top of tank downward to surface of oil in tank. Crude oil transportation and integrity management •limit bs&w to 05 percent by volume and report results to phmsa in • tariff excursion procedure.
Hysterectomy is a major surgical procedure that has risks and benefits, and affects a woman's hormonal balance and overall health for the rest of her life. The bs&w content of crude oil is determined using small centrifuges that are driven by hand or by electric motor a small measured volume of sample is diluted with solvent and placed in graduated glass containers that then are inserted into the centrifuge and spun for a few minutes at speeds of 2,000 to 4,000 rev/min. Bs&w contained in the crude must not exceed the maximum levels specified by the crude purchaser—usually less than 1% to determine this, the lease pumper should use the following procedure.
D4007 - 11(2016)e1 standard test method for water and sediment in crude oil by the centrifuge method (laboratory procedure) , centrifuge, centrifuge tube, crude oil, laboratory procedure, sampling, sediment and water, solvent,. Sampling for both api and bs&w 2 plastic bottles must not be used for sampling as there is a risk of a build-up of static charge and the container cannot be earthed to ground crude oil samples can only be sampled into earthed steel sampling containers. Trus & prostate biopsy procedure patients may be instructed to discontinue blood-thinning medications (eg, aspirin, ibuprofen) for a week to 10 days prior to undergoing trus and prostate biopsy an antibiotic (eg, ciprofloxacin) may be prescribed prior to and for a couple of days following the procedure to help prevent infection.
By aggregating surgeries and procedures that have high risk, yet few in annual volume, we can ensure that essential resources are available at the treating hospital and, as important, institutional volumes are at a level to provide the expertise resulting in fewer complications and improved outcomes. Read the bs&w measurement directly from the 0% to 200% calibrated tubes double the readings (to account for the solvent) to determine the bs&w content of the oil from the 0% to 100% calibrated tubes (ie reading of 25ml is to be recorded as 5ml. According to bs en 206-1, the specifier is also responsible for ensuring that the specified proportions do not result in damaging alkali-silica reaction (asr), but see a81 for an alternative.
Free essys, homework help, flashcards, research papers, book report, term papers, history, science, politics. Centrifuge for 10 minutes (tests at each field will be required to determine if 10 minutes is sufficient to drop out all bs&w 10obtain readings of combined basic sediment and water directly in percentages from the. Procedures for water by distillation, test method d 4006 (api mpms chapter 102) (note 1), and sediment by extraction, test method d 473 (api mpms chapter 101), shall be used.
Power supplies, to achieve oil purity of 01% bs&w or better desalting more important than water content to a refiner is the salt content of the oil depending on. Basic sediment and water (bs&w) is a technical specification of certain impurities in crude oil when extracted from an oil reservoir , the crude oil will contain some amount of water and suspended solids from the reservoir formation. Gauging manual 2 table of contents gaugers summary 4 pre-departure checks 4 procedure for gauging tanks 6 used to determine bs+w of the tank. Bs&w can be determined using laboratory standards eg astm standard d96, d4007 or the api document sediment and water, chapter 10, section 2, 'determination of water and sediment in crude oil by the centrifuge method.
